Roof Pitch Vs Slope

The pitch of the roof pertains more to the actual construction of the house whereas the slope is more relevant to the roofing of your house.

Roof pitch vs slope.

This can be very effective for certain ranch styles porch rooftops or modern geometric rooftops. If the slope is 4 12 the pitch for the 24 foot span is 1 6. Roof pitch can be a health and safety issue on homes in geographic areas that experience heavy snow and rain. Pitch and slope do not mean the same thing.

And pitch is a fraction derived by dividing the rise by the entire span. If the pitch is 1 3 the slope is 8 12. A roof that rises 4 inches for every 1 foot or 12 inches of run is said to have a 4 in 12 slope. Slope is the ratio measured in inches per foot.

A steep slope to a roof makes it more difficult for wet snow to accumulate and put undue stress on your roof. Because slope affects how water is shed from a roof surface and determines the limits for using asphalt shingles understanding how to measure the slope of a roof may be valuable to a home inspector. The steepness of your roof also known as the roof pitch or slope is an important decision to make for your property especially when considering residential roofingchanges. Slope minimums for various roof coverings.

The slope ratio represents a certain amount of vertical rise for every 12 inches of horizontal run. Picking a low pitch or slope for your roof will give your rooftop a flatter more box like look. Plus since the low pitch requires fewer materials and less work than the steep pitch it comes at a lower cost. If the rise is 6 inches for every 12 inches of run then the roof slope is 6 in 12 the slope can be expressed numerically as a ratio.

Remember slope is expressed as a ratio and in inches per foot.
